ABSTRACT:
Closing arrangement for sliding doors adapted to move between closed and open positions along a lengthwise guide track. The arrangement includes a rotor operatively connected with connecting links connected to the door and arranged to move along the guide track. Brake arrangement is mounted with a drive member mounted in coaxial alignment with the rotor shaft. The closing arrangement is provided with a coupling device which is operatively connected to the rotor shaft and comprises an electromagnetic coupling and a friction coupling mounted on a common shaft. The coupling device prevents an inadvertant backward movement of the open sliding door to its closed position.
